Incorruptible? Effigy? There is definitely some wax involved. The caption next to this figure in his space age crystal coffin read:
Corpo di San Giovanni Leonardi (Diecimo-Lucca 1591-Roma 1609) Fondatore dell'Ordine della Madre di Dio Cofondatore del Collegio di Propaganda Fide, Patrono dei Framacisti." (Or, as translated by Google, "Body of St. John Leonardi (Diecimo Lucca-1591-Rome 1609) Founder of the Order of the Mother of God, co-founder of the College of Propaganda Fide, Patron of Pharmacists.)As seen at--if I remember correctly--his shrine at Santa Maria of Campitelli church in Rome. More on this saint can be found here. More from Italy to come very soon.
